Étude de l'immunopathogénèse dans le déficit immunitaire commun variable et les erreurs innées de l'immunité associées
Cette étude observationnelle vise à caractériser les anomalies immunitaires chez les individus atteints de Déficit Immunitaire Commun Variable et d'Erreurs Innées d'Immunité associées, d'établir le schéma et le rythme de progression de la maladie, et d'évaluer la dysfonction ou les dommages organiques résultant de ces anomalies immunitaires.

Date de début de l'étude : 15 janvier 1990
Date à laquelle le premier participant a commencé l'étude.The purpose of this protocol is to carry out laboratory studies concerning the immunopathogenesis of Common Variable Immunodeficiency (CVI) and related inborn errors of immunity (IEI). Additionally, we aim to document and track the progression of known complications of these immune abnormalities. Complications associated with CVI include recurrent respiratory, granulomas, pulmonary insufficiency, gastrointestinal bacterial infections, enteropathy, nodular regenerative hyperplasia, lymphoid malignancy, and various autoimmune manifestations. Patients with CVI and related IEI will be enrolled into this natural history study. Protocol procedures will include baseline measurements of and changes in lab studies. First- or second-degree genetically related family members (limited to mother, father, siblings, grandparents, children, aunts, uncles, and first cousins of an affected patient) may also be screened for clinical, in vitro, and genetic correlates of immune abnormalities. Changes in the patients' clinical state will be measured to determine the precursors of disease complications. This may lead to developments in improving preventive measures and novel treatment options for this population.

Critères
* INCLUSION CRITERIA: * Must have a verifiable diagnosis of common variable immune deficiency as defined by a decrease both in IgG and at least one other Ig isotype to below two standard deviations of normal control levels OR B-cell immunodeficiencies related to CVI (defined as selective IgA deficiency, selective IgG isotype deficiency, agammaglobulinemia, and hypogammaglobulinemia associated with Epstein-Barr virus infection), or hypogammaglobulinemia associated with other related inborn errors of immunity. This includes patients with a defined diagnosis of Blau or Yao Syndrome. * Must be 2 years old or greater. * Patients with repeated infections and suspected of having an inborn error of immunity. * Patients must be referred by their primary medical care provider. * On investigator s discretion, unaffected family members (mother, father, siblings, children, grandparents, aunts, uncles, and first cousins) may be asked for the provision of blood or buccal specimens for research purposes. * Patients who are lactating, may be eligible and will only undergo tests and procedures, and/or receive medications for which data exists that proves that they are minimal risk to the child. * Pregnant women will not be newly enrolled onto this protocol, however existing patients who become pregnant while on study will remain on study, as literature about pregnancy in CVI patients is sparse and outside providers have minimal knowledge about managing CVI during pregnancy. Pregnant women will only undergo tests and procedures, and/or receive medications for which data exists that proves that they are minimal risk to the fetus. Pregnant unaffected relatives will not be enrolled in this study). * All patients must be willing to have research samples stored for future studies and/or other research purposes. * NIH staff and family members of study team members may be enrolled in this study as this population may meet study criteria. Neither participation nor refusal to participate as a subject in the research will have an effect, either beneficial or adverse, on the participant s employment or position at the NIH. Every effort will be made to protect participant information, but such information may be available in medical records and may be available to authorized users outside of the study team in both an identifiable and unidentifiable manner. The NIH investigator will provide and request that the NIH staff member review the Frequently Asked Questions (FAQs) for Staff Who are Considering Participating in NIH Research and the Leavy Policy for NIH Employees Participating in NIH Medical Research Studies (NIH Policy Manual 2300-630-3). EXCLUSION CRITERIA: * Presence of other medical illnesses that would preclude individuals from undergoing routine diagnostic testing or testing for immunologic features of immunodeficiency. * Presence of a condition or treatment, such as HIV, cytotoxic chemotherapy or malignancy, that in the investigator s opinion could interfere with evaluation of the condition under study. * Pregnancy at the time of enrollment. * Inability of an adult participant to provide informed consent for themselves (decisionally impaired adult).
